Yimmy's place is perfectly located near the BTS Surasuk station, in a quiet street. The sweet little cafe just next door does both western and local breakfast, great if you are travelling with difficult kids.
The apartment is perfectly clean, a simple setup with two bedrooms each having their own ensuite bathroom.
Yimmy is a friendly and fantastic host and replied quickly (within minutes) to all of our questions, with very clear instructions. She even has an office at the apartments so you will never feel abandoned!
Best option for travel to the temples is to take the BTS one stop to the river and jump on the ferry (don't get the tourist trap ones, paper tickets for the ferry are sold by ladies at a ramshackle desk).
